The existing appliance is in a home recently purchased and I have no owner’s manual. My question is: Is the fan in the oven supposed to run intermitenly or continuous??
I am not sure, with luck someone with this unit will jump in.
Here is a manual for a SKSS unit that should be close to yours

The unit has a couple fans,
The convection fan in the oven usually only runs when you are convection cooking.
The cooling fan may run all the time, this I am not sure on. See pages 10 and 20 in the manual.
